Definitions

  • the present invention relates to a device for optimizing the driving of a railway vehicle.
  • the energy consumption of a rail vehicle is directly related to the speed of it.
  • a device for optimizing the driving of a rail vehicle comprising means for determining a target speed, and means for indicating modification instructions, are already known. an instantaneous speed of the railway vehicle to approach the target speed.
  • Such a device indicates, generally in real time, instructions to the driver of the vehicle, so that it undertakes actions corresponding to these instructions (acceleration, braking, coasting ...) to approach the instantaneous speed the vehicle of the target speed.
  • This target speed is the most optimized speed to minimize the vehicle's energy consumption, given various constraints, including schedule requirements, speed limits and comfort requirements.
  • the object of the invention is in particular to improve the efficiency of such an optimization device.
  • the subject of the invention is particularly a device for optimizing the driving of a railway vehicle, comprising means for determining driving instructions from a target speed, and means for indicating the driving instructions for a driver of the railway vehicle, with a view to approaching an instantaneous speed of the railway vehicle of the target speed, characterized in that the determination means comprise means for studying the behavior of the driver, the target speed being determined according to this behavior of the driver.
  • each driver chose his own way of accelerating and braking to reach the target speed, in order to respect the schedules.
  • each driver has his own way of adapting to the instructions that are transmitted to him (reaction time, action time, possible errors ). This leads to a disparity of energy consumption according to behaviors of various drivers, and more particularly energy overconsumption.
  • the optimization device determines the driving instructions taking into account the behavior of the driver.
  • the optimization device specifically adapts to this driver and his driving habits.
  • a device 10 for optimizing the driving of a railway vehicle intended to equip this railway vehicle.
  • the railway vehicle Since the railway vehicle is intended to run on a railway, it follows a predefined path, so that it is possible to provide an optimal speed of movement of the rail vehicle, in particular to minimize the energy consumption of the vehicle, while taking into account the schedules that must respect this vehicle, among other parameters.
  • the railway includes in particular a plurality of stations, to which the railway vehicle is likely to stop.
  • the optimization device 10 comprises means 12 for determining driving instructions from a target speed V c .
  • the target speed V c corresponds, for example, to an optimal speed for limiting the energy consumption of the railway vehicle.
  • This target speed V c is advantageously determined in real time, this target speed V c constantly changing over time, in particular as a function of the position x (t) at which the rail vehicle on the railway is located.
  • the optimization device 10 In order to be able to determine this position x (t), the optimization device 10 conventionally comprises locating means 14, for example a satellite guide device.
  • the determination means 12 comprise means 16 for calculating the target speed V c in real time, comprising a calculation algorithm determining the target speed V c as a function of parameters, which will be described later.
  • Such real-time computing means 16 are particularly suitable for taking into account a possible delay or an advance on the schedules that the rail vehicle must respect.
  • the determination means 12 also comprise means 18 for comparing an instantaneous speed V i of the railway vehicle with the target speed V c indicated by the calculation means 16.
  • a target speed interval is defined around the speed target V c , and the comparison means 18 compare the instantaneous speed V i with this target speed interval.
  • the optimization device 10 further comprises means 20 for indicating the driving instructions to a driver 22 of the railway vehicle.
  • the comparison means 18 provide the results of the comparisons to the indication means 20.
  • the driving instructions notably comprise instructions for modifying the instantaneous speed V i in order to approach the target speed V c , in particular an instruction for increasing the speed when the instantaneous speed V i is lower than the target speed.
  • V c a speed reduction instruction when the instantaneous speed V i is greater than the target speed V c
  • a speed maintaining instruction when the instantaneous speed V i is substantially equal to the target speed V c .
  • the indication means 20 may comprise different display devices that can be envisaged.
  • the indicating means 20 comprise a display panel, in particular a display screen, capable of displaying driving instructions in the form of driving instruction pictograms.
  • the indication means 20 comprise a head-up display device capable of displaying the driving instructions in a field of view of the driver.
  • the conductor 22 acts on conventional means 24 traction level control, generally comprising a control lever traction / braking.
  • This control lever is actuated by the driver of the railway vehicle, to apply to the railway vehicle a level of traction or braking to change the instantaneous speed V i , desired by the driver, to approach the target speed V c .
  • the determination means 12 comprise means 26 for recovering these parameters, notably comprising database storage means 28, storing some of these parameters which are functions of the position x (t) of the vehicle on the railroad track.
  • First parameters are formed by environmental mapping data, more particularly data relating to the shape of the railway, particularly relating to the locations of slopes and descents, turns and straight lines.
  • the mapping data also includes any other specific local data, such as speed limits, intersections, and / or zones. so-called dangerous (exit of turn, pedestrian zones). This mapping is important because it greatly influences the choice of target speed in any position of the vehicle on the track.
  • the mapping data are for example stored in the storage means 28.
  • the driving procedure data is a general driving instruction, usually defined by an operator, that the driver must follow.
  • driving procedures impose, for example, a maximum speed when arriving at the station, as well as acceleration and braking force limits of the vehicle, for reasons of passenger comfort.
  • Time tables inform the time available to complete a mission between two stations. These data are used to define the acceleration or braking profile to travel the distance corresponding to the mission. Indeed, for example, it accelerates further to cover a distance of 800 meters in 2 minutes rather than to travel the same distance in 4 minutes.
  • the determination means 12 of the optimization device 10 furthermore comprise self-adaptive means 30 for studying the behavior of the conductor 22, the target speed V c being determined at each moment based on this behavior of the driver.
  • These study means 30 are configured to produce a neuromuscular model of the conductor 22, made from the driving instructions transmitted to the driver and the command applied by it.
  • the behavior analysis means 30 are configured to recursively determine parameters related to the behavior of the driver, from an identification algorithm, with a view to self-adaptation of the target speed and instructions to be transmitted to the driver. 22. More particularly, the identifications of these parameters are recursively updated according to a predictive model for calculating errors between the instruction carried out and the instruction transmitted to the driver.
  • the driver 22 intervenes, just like the vehicle and its consumption model, in determining the target speed.
  • the delay, the neuromuscular time and the gain are taken into account for the determination of the target speed by updating the calculation model parameters.
  • the update is performed after each parameter identification.
  • the determining means 12 determine the target speed V c by means of an optimization algorithm, determining in real time the target speed V c on the basis of the parameters mentioned above.
  • This optimization algorithm is configured to determine possible speeds to achieve the mission in the given times and respecting the environmental constraints. The speed which makes it possible to minimize the traction force for the entire course is then retained and transmitted to the driver 22. This target speed is calculated every second.
  • the optimization device makes it possible to generate instructions which consider the evolution of the behavior of the driver in real time to improve the optimization of the energy consumption.
  • the device 10 is self-adapting to the behavior of the driver (thanks to the identification of the parameters of the driver 22), which no other known eco-driving aid system does.
  • the device 10 makes it possible to give an eco-driving instruction adapted to the conductor 22 while respecting the stress of minimizing the traction force in order to reduce the energy consumption.
  • the system running continuously, the execution of the driving task in the time allotted by the time table (in nominal situation) respecting the speed limits is guaranteed.
